Gas tungsten arc welding (GTAW), also known as tungsten inert gas (TIG) welding, is an arc welding process that uses a non consumable tungsten electrode to produce the weld. Gas tungsten arc welding is most commonly used to weld thin sections of stainless steel and light metals such as aluminum, magnesium, and copper alloys among other metal properties except for lead and zinc. The process grants the operator greater control over the weld than competing procedures such as shielded metal arc welding and gas metal arc welding, allowing for stronger, higher quality welds.
The electric arc was discovered and developed by Humphry Davy in 1800. C.L Coffin also had the idea of welding an inert gas atmosphere in 1890, but even in the early 1900, welding non-ferrous materials like aluminum and magnesium remained difficult. To solve the problem, bottled inert gasses were used in the beginning of 1930. The electric arc process was perfected in 1941, and became known as heliarc or tungsten inert gas welding because it utilized a tungsten electrode and helium as a shielding gas. In 1953, a new process based on GTAW was developed, called plasma arc welding. It affords greater control and improves weld quality by using a nozzle to focus the electric arc, but is largely limited to automated systems, whereas GTAW remains primarily a manual, hand-held method.
Advantages:
1- Concentrated Arc
2- No Slag
3- No Sparks & No Spatter
4- Little To No Smoke Or Fumes
5- Welds More Metals And Metal Alloys Than Any Other Process
6- Good For Welding Thin Materials
Disadvantages:
1- Slower travel speeds than other processes
2- Lower filler metal deposition rates
3- Hand-eye coordination is a required skill
4- Brighter UV rays than other processes
5- Equipment costs can be higher than other processes
6- Concentrations of shielding gas may build up and displace oxygen when welding in confined areas

By Ben Needles
The harbingers of doom are constantly warning of a decrease in property sales and the effects this is having not only on the property market but on the economy as a whole. Today, predictions for property sales within the UK are particularly downbeat, a recent report from the Royal Institution of Chartered Surveyors gloomily predicted that this year could see property sales fall by as much as thirty percent.
But this situation is in a way a self fulfilling prophesy, understandably estate agent are attempting to downplay the fears but as the media constantly reports the bad news, the general public are drawn to make certain conclusions on the state of the property market in the UK.
As the media is now almost reporting further falls in property sales daily, the knock on effects are becoming clearly evident. Most startlingly buyers are in fact holding tight until the proposed crash is going to occur. Agents are understandably trying to dispel this myth that in six months time that property prices will be so low that everyone will be able to buy and hence sales will increase. Preferable for the agents is a steady number of sales, even if in decline; if buyers continue to wait there is no surety that the prices will collapse, remember that sellers can be just as stubborn as buyers.
Even if buyers do continue to wait however it can be seen as a ray of sunshine for those who work in property sales. It shows that on the horizon there are many who are willing to buy but are simply waiting for cheaper prices. However while some may be able to grab bargain, many will most likely be left unsatisfied.
The drop in property sales is not just about buyers waiting for lower prices though; the current mortgage crisis has much to do with the problems in the market. While in past years it has been the case that buyers have been able to secure one hundred percent mortgages the situation is now wholly different.
As the American financiers found that they have overreached themselves and are facing record numbers of non-payments the ramifications have quickly leapt across the pond. The current situation in the UK is that lenders are being far more careful with their money, meaning that first time buyers and even existing home owners are finding it hard to make progress on the property ladder.
It is now advisable to have a considerable deposit if you are wishing to buy a property; for the sake of property sales in the UK the general hope is that there is a wealth of buyers out there that have these funds. With unresponsive lenders all hopes are pinned on peoples savings. As we have seen however in the lat few years there are not many people who having been saving, the consumer culture has led to a situation where there is nearly an entire generation dependent upon their credit cards for financial support. As seemingly everything in life becomes more expensive it is understandable that people are tightening their purse strings and renting instead of buying.
The property figures are just a symptom of a wider issue of the publics financial situation, as properties are the most expensive thing most people will buy in their lifetime; it is unsurprising that they should be hardest hit by these frugal times.
This rather gloomy outlook is not certain however, predicting the property market is a notoriously difficult task, even with years of experience within the estate agency industry. Ultimately people will always need homes and hence it will survive. As anyone with an elementary understanding of economics will be able to grasp, capitalism operates along a boom and bust schedule and as the property market has been clearly booming in recent years, sooner or later the cycle had to move to a period of slowdown.

Where Can I Buy Plasma Cutters Online?
By Kristi Ambrose
There are actually several thousand places you find plasma cutters online. But the question you really should be asking is where can you find (insert brand and model here) plasma cutters. Obviously with any other equipment there are always different brands, styles, shapes, sizes and models. Different models will cut different types of metals, and different brands will be rated higher than others. It’s a really good idea to go on Google and look for reviews on certain plasma cutters.
One of my favorite places to go for ANY review is Amazon, because there is always at least one person that has bought the product, used the product and is willing to sacrifice a few minutes of his or her time to let everyone else know what they thought of the product. You can also check out YouTube. YT has some really great videos of people using different cutters, so you the consumer can see how they work, how well they work and what kind of materials you can cut through.
I also found a few videos on there of people “testing” how strong certain cutters were compared to other cutters. People are usually more than willing to give advice on products they own or have owned in the past, so just do a little searching around and see what you can come up with!
To find different places to buy plasma cutters you can try the following places. Of course as said above there are several thousand places you can look at but just for the sake of the article I’m willing to supply a few websites that have been highly rated among users of plasma cutters. So, check these sites out:
HyperTherm
CyberWeld
MillerWelds
PlasmaCutter
Obviously another aspect you’re going to want to take a look at is prices. Now with the old plasma cutters they used to cost around $1000 USD or more which was primarily the reason that you only found cutters inside auto shops or other professional shops. But nowadays you can find a really nice plasma cutter for well around $300 depending on the brand, style, model, etc. So, make sure you look around at a few different places.
Another really great thing you can do to save yourself some time is go to comparison shopping sites find the correct category usually something like nextag/homeandgarden/homeimprovement/plasmacutters. In that case you will see brands like Miller, Hobart, Soar, Firepower, etc. And then you can see different prices right next to each other (without looking at 50 different stores online). These comparison shopping sites also might offer other things such as reviews and comments from other users, so look out for that as well!
